Tried converting the classifiers to run in a TPL dataflow pipeline

[Fraaankes]

By using the excelent, but often forgotten library https://docs.microsoft.com/en-us/dotnet/standard/parallel-programming/dataflow-task-parallel-library its possible to build some very cool pipelines for async/background processing, and then pushing the results to the UI as they become available.
In the simplest of cases it could probably also be replaced by Rx.

Thanks for the contribution. I've received a few different approaches, and I'll be writing about all of them in a future article. I want to make all of the contributions available as separate branches so folks can explore them in the future. I'll let you know when that's done.
